Patent GB-624698-A (GB)
Title: Electrodes for piezoelectric crystal elements and methods of applying same
IPC: H01L41/047
Filed: 1946-04-18
Abstract: 624,698. Coating with metals. BRUSH DEVELOPMENT CO. April 18, 1946, No. 11991. Convention date, May 4, 1945. [Class 82(ii)] [Also in Group XL(c)] The electrodes for a piezo-electric crystal are formed of a layer mainly of a metal such as aluminium, beryllium or magnesium which adheres firmly to the crystal surface, followed by a layer mainly of a highly conductive and preferably less corrodible metal such as gold, silver, palladuim or platinum which adheres firmly to the first metal but which would adhere less firmly if applied directly to the crystal. The two processes of deposition are preferably carried out in a vacuum and without releasing the vacuum, and the second process may be commenced before the first is completed so that the junction of the layers is formed by a mixture of the metals. Fig. 3 shows the deposition being carried out within a bell-jar 21 evacuated by pump 24. The crystal plates 29 rest on a curved holder 28 below a tungsten filament 27 which carries short lengths or aluminium and gold wire 41, 40. The filament is heated by an electric current causing the evaporation to commence first of the aluminium and then of the gold. When two distinct layers are required the two metals may be hung on separate filaments which are heated in turn, Fig. 4 (not shown). The filaments are preferably kinked to prevent the metals flowing along the filaments. The aluminium or gold may alternatively be coated on the filaments or may be evaporated from crucibles. Burnishing the final electrode improves adhesion.

A hardening liquid, e.g. potassium and sodium silicate, and silicic acid, is sprayed on to the web at 20. The web is then cut by a disc-knife or a grinding-wheel mounted on a transversely-moving carriage 17 which is carried by a main carriage which moves longitudinally, together with a conveyer belt 12; the asbestoscement slabs L being then carried past infra-red lamps directed against both sides of the slabs. The slabs are accelerated by a roller-conveyer and are piled up, with the aid of an air-blast, on to a carriage which is raised from its rails by an hydraulic jack and lowered gradually, in cooperation with a feeler as the slabs are piled up. The surface layers of the slabs may be of better quality than the interior, and they may be coloured.

Title: Surface treatment of polyethylene terephthalate films
Inventor: GATES WILLIAM ELLIOTT FREW
IPC: B29C59/10
Filed: 1955-04-29
Abstract: The surface bonding properties of a polyethylene terephthalate film, which has been molecularly oriented by drawing but has not been heat-set, for printing inks and other materials, are improved by subjecting a surface of the film to a high-voltage electric stress accompanied by corona discharge, for example, as described in Specification 715,914.  In the example, a film of polyethylene terephthalate 0.0005 inch thick is produced by melt extrusion into water and the quenched film is drawn at 80 DEG  C. both longitudinally and laterally to three times its original dimensions. Short lengths of the drawn film are subjected to corona discharge in the apparatus described in Specification 715,914, the undersurface of the fixed electrode being coated with polytetrafluoroethylene.  The voltages delivered to the system range from 10,000 to 30,000 volts in 5,000 volt steps, the corresponding amperages being 5, 6, 9, 12 and 15 milli-amperes and a succession of short lengths of the film being exposed to 10,000 volts, 15,000 volts and so on.  Aniline and gravure type printing inks are spread over the surface of the treated film, which is then heat-set by gripping it firmly around its edges, heating it to 180 DEG  C., and immediately allowing it to cool to room temperature.  In all cases the ink adheres well to the treated surface.  The Provisional Specification refers also to Specifications 603,840 and 609,797.
